My place to write about tech and DIY

This will be a very short article or rather a note and link collection on NodeJS. If you browsed through my blog, you have probably stumbled upon my beginner augmented reality project, where I wanted to create a real-time temperature and humidity monitor using Open Hybrid. Installing an augmented reality app on the Raspberry Pi Creating…

I wrote this article on the RetroPie setup some time ago, but I’m still getting a lot questions and comments on this topic. I actually thought that with the last couple emulator station updates came some improvements to this process. As I have not touched my system for quite some time, I simply do not…

As part of my “make my home a bit smarter” projects, I wanted to add simple motion detection via motion sensor to a Raspberry Pi. This is the first project with a hc-sr501 motion sensor I tried. The goal is to combine the sensor with an esp8266, but this is another project (as I’m still…

If you have landed on this site because you are looking for the tutorial on the sourdough incubator, this is the wrong post. Click here to go to: How to build an Arduino based sourdough incubator. This is a new series of posts. I want to try to document some of the ideas I have, which I probably never…

Installing a CM108 Audio Controller on the Raspberry Pi With the publication of the post on Raspberry Pi + Alexa Voice Service I wanted to try this out by myself. Even though the hardware requirements besides the raspberry pi are pretty low, I was missing a reasonable microphone. As I’m a big fan of Aliexpress I had…

Creating an object for augmented reality on Raspberry Pi This is the third article in my series on augmented reality, following: Installing an augmented reality app on the Raspberry Pi Installing a DHT22 temp and humidity sensor on the raspberry pi In this tutorial I will create my first object to use in OpenHybrid. This…

Why build an Arduino based sourdough incubator? Living in a foreign country usually leads to some challenges and some things you miss from your home country. For me this is good sourdough bread, which is pretty hard to get in Switzerland and kind of expensive. So since I’m cheap ;-), I thought why not make some…

This is part of my series on creating my own augmented reality app, which I started here with the setup of OpenHybrid. I Like to use the DHT22 as an object, that I wand to control or read sensor data from. Therefore I have to install it first and make sure it is running correctly….

Installing an augmented reality app on the Raspberry Pi? How did I end up playing around with augmented reality? I recently published a paper on the usage of augmented reality in marketing, finding out that there is no real marketing via augmented reality yet. As it became clear that almost all cases we had a…
